Or rather the question should be: how to make a signature brush in Photoshop? Very easy. For this you need an interesting pattern (brush) and beautiful font.
Where to get original beautiful brushes for Photoshop? The following options:
1. Searching for "brushes for Photoshop".
2. Creating a brush yourself by drawing it in the editor.
If a brush is selected (not drawn), you need to download and install ше. If we are not satisfied with the standard set of fonts, select what you like in Fonts.
The brushes are set, the fonts also, now you need to create your own beautiful signature and make it your personal brush. Create a new document: File>New (or Ctrl+N). Select Transparent for the background, so that you needn't have to separate the brush from the background.
Select one of the installed brushes:
Apply the brush on the transparent background:
Now you need to add your signature over the pattern. Save it as a Text element with the font you chose.
See that the pattern kills the signature, then do the following: choose layer with background, on which the pattern is placed and change its Opacity until you're not satisfied with the result.
Save the brush: Edit -> Define Brush Preset... and give it a name.
You can do anyhing with the created brush: choose the colour, change the size, transparency, etc.:
One can do wonders with brushes, not only significantly simplifying the process of tagging your photos, but also using them as a design element of your blog, site, banner, page.
I will be glad to see links to your signatures made on Photoshop in the comments :)
Enjoy your creativity, dear users!
